Think it out before you purchase your poker domain. I like to use www.GoDaddy.com
to purchase my poker domains. They have excellent service 24/7. Choose your domain wisely so that people take your site serious. When you buy your domain, buy the .net .org too so nobody gets on your bandwagon. Beware of Trademark infringements. I do not personally believe it is wrong to buy domains that have WPT, or WSOP, or something like that in it, but they are likely to send you a letter form their lawyer. If you want to have a site that is about poker shirts for example, try to have those two words in the name. Try to keep the domain name to 3 words or less, no numbers, and no dashes.
